Development and Use of the Anti-CD19 Chimeric Antigen Receptor T-Cell Therapy Axicabtagene Ciloleucel in Large B-Cell Lymphoma: A Review.

ABSTRACT:

Importance

Axicabtagene ciloleucel, an anti-CD19-CD28-CD3? chimeric antigen receptor T-cell therapy, was the first US Food and Drug Administration-approved, genetically engineered T-cell therapy for adults with relapsed or refractory large B-cell lymphoma (LBCL) after 2 or more lines of systemic therapy. There has not been a US Food and Drug Administration-approved product for these cancers in more than 4 decades.

Observations

Unlike traditional anticancer therapies, axicabtagene ciloleucel is a patient-specific, live-cell product that has unique requirements for manufacturing, shipping, and storage, as well as for its administration and management of its adverse events. In addition, axicabtagene ciloleucel has demonstrated efficacy in patients with refractory LBCL. This review presents a timeline of the rapid clinical development of axicabtagene ciloleucel from bench to bedside, highlights how axicabtagene ciloleucel satisfies an unmet medical need for treatment of refractory LBCL, outlines the logistics of the production process and administration of axicabtagene ciloleucel, describes its mechanism of action, and summarizes the results of the pivotal study. This review also provides a survey of adverse events, with attention to the kinetics of their clinical presentation; discusses the management of adverse events; and offers suggestions for appropriate patient selection for safe administration of axicabtagene ciloleucel.

Conclusions and relevance

The integration of axicabtagene ciloleucel therapy into standard-of-care practice for relapsed/refractory LBCL is the beginning of a paradigm shift in the treatment of patients with LBCL and is likely to lead to improvements in their survival and curability. Timely referral to centers offering the therapy is necessary for optimal patient outcomes.

Project description:Axicabtagene ciloleucel is the first U.S. Food and Drug Administration-approved autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy for the treatment of patients with relapsed or refractory large B-cell lymphoma after ?2 prior systemic therapies. Although axicabtagene ciloleucel is administered only at authorized treatment centers, community oncologists play a critical role in the CAR T-cell treatment journey, recognizing potentially eligible patients for referral and then, after treatment, closely collaborating with treatment centers to monitor and manage patients long term. ZUMA-1, the pivotal, multicenter, phase I/II study of 108 patients treated with axicabtagene ciloleucel, resulted in an objective response rate of 83%, including 58% complete responses. With a 27.1-month median follow-up, 39% of patients had ongoing responses. CAR T-cell therapy is associated with the potentially life-threatening adverse events (AEs) of cytokine release syndrome and neurologic events, which generally occur early after treatment. In ZUMA-1, cytokine release syndrome and neurologic events were generally reversible and grade ?3 cytokine release syndrome and neurologic events occurred in 11% and 32% of patients, respectively. Frequent prolonged AEs included hypogammaglobulinemia, B-cell aplasia, and cytopenias requiring supportive care until recovery of hematopoietic function. Rate of treatment-related mortality was low, at <2%. With appropriate management of common AEs, axicabtagene ciloleucel offers the potential for long-term durable responses in patients who otherwise lack curative treatment options. IMPLICATIONS FOR PRACTICE: Community oncologists should be familiar with key aspects of chimeric antigen receptor (CAR) T-cell indications and eligibility to help recognize and refer potential patients for this paradigm-changing treatment option at the appropriate time during the disease course. To ensure optimal long-term outcomes for patients who have been treated with CAR T-cell therapy, oncologists must also be familiar with common prolonged AEs and their monitoring and management.

Project description:BACKGROUND:In a phase 1 trial, axicabtagene ciloleucel (axi-cel), an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, showed efficacy in patients with refractory large B-cell lymphoma after the failure of conventional therapy. METHODS:In this multicenter, phase 2 trial, we enrolled 111 patients with diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, or transformed follicular lymphoma who had refractory disease despite undergoing recommended prior therapy. Patients received a target dose of 2×106 anti-CD19 CAR T cells per kilogram of body weight after receiving a conditioning regimen of low-dose cyclophosphamide and fludarabine. The primary end point was the rate of objective response (calculated as the combined rates of complete response and partial response). Secondary end points included overall survival, safety, and biomarker assessments. RESULTS:Among the 111 patients who were enrolled, axi-cel was successfully manufactured for 110 (99%) and administered to 101 (91%). The objective response rate was 82%, and the complete response rate was 54%.With a median follow-up of 15.4 months, 42% of the patients continued to have a response, with 40% continuing to have a complete response. The overall rate of survival at 18 months was 52%. The most common adverse events of grade 3 or higher during treatment were neutropenia (in 78% of the patients), anemia (in 43%), and thrombocytopenia (in 38%). Grade 3 or higher cytokine release syndrome and neurologic events occurred in 13% and 28% of the patients, respectively. Three of the patients died during treatment. Higher CAR T-cell levels in blood were associated with response. CONCLUSIONS:In this multicenter study, patients with refractory large B-cell lymphoma who received CAR T-cell therapy with axi-cel had high levels of durable response, with a safety profile that included myelosuppression, the cytokine release syndrome, and neurologic events.

Project description:The ZUMA-7 (Efficacy of Axicabtagene Ciloleucel Compared to Standard of Care Therapy in Subjects With Relapsed/Refractory Diffuse Large B Cell Lymphoma) study showed that axicabtagene ciloleucel (axi-cel) improved event-free survival (EFS) compared with standard of care (SOC) salvage chemoimmunotherapy followed by autologous stem cell transplant in primary refractory/early relapsed diffuse large B-cell lymphoma (DLBCL); this led to its recent US Food and Drug Administration approval in this setting. We modeled a hypothetical cohort of US adults (mean age, 65 years) with primary refractory/early relapsed DLBCL by developing a Markov model (lifetime horizon) to model the cost-effectiveness of second-line axi-cel compared with SOC using a range of plausible long-term outcomes. EFS and OS were estimated from ZUMA-7. Outcome measures were reported in incremental cost-effectiveness ratios, with a willingness-to-pay (WTP) threshold of $150 000 per quality-adjusted life-year (QALY). Assuming a 5-year EFS of 35% with second-line axi-cel and 10% with SOC, axi-cel was cost-effective at a WTP of $150 000 per QALY ($93 547 per QALY). axi-cel was no longer cost-effective if its 5-year EFS was ≤26.4% or if it cost more than $972 061 at a WTP of $150 000. Second-line axi-cel was the cost-effective strategy in 73% of the 10 000 Monte Carlo iterations at a WTP of $150 000. If the absolute benefit in EFS is maintained over time, second-line axi-cel for aggressive relapsed/refractory DLBCL is cost-effective compared with SOC at a WTP of $150 000 per QALY. However, its cost-effectiveness is highly dependent on long-term outcomes. Routine use of second-line chimeric antigen receptor T-cell therapy would add significantly to health care expenditures in the United States (more than $1 billion each year), even when used in a high-risk subpopulation. Further reductions in the cost of chimeric antigen receptor T-cell therapy are needed to be affordable in many regions of the world.
